Both Philip and Andrew are philosophy students whose interests converge around the philosophy of technology broadly understood. Philip's interest is specifically aimed toward the ethics of Transhumanism and depictions of Transhumanism in works of fiction. On the other hand, Andrew finds himself more focused on religious behavior in the technological world. While the two perspectives might not seem that close, there is certain to be an overlap in Andrew and Philip's shared understanding of how technological phenomena play (...) a crucial role concerning religion and society.

In this paper, I consider the difficulty of distinguishing between science fiction and philosophy. The boundary between these genres is somewhat vague. There is a “neutral zone” separating the genres. But this neutral zone is often transgressed. One key distinction considered here is that between entertainment and edification. Another crucial element is found in the importance of the author’s apparent self-consciousness of these distinctions. Philosophy seeks to edify, and philosophers are often deliberately focused on thinking about the question of the (...) borders that distinguish genres. Science fiction is more interested in entertainment, and narrative authors tend to care less about policing the border. This distinction is a pragmatic one. And canonical authors often violate the boundary. I examine key authors to make this point, including Plato, Kant, and H.G. Wells. My discussion shows that these canonical authors wandered into the neutral zone in their own work, reminding us that the boundaries we draw around genres are arbitrary and subject to transgression.

As the Zika virus pandemic continues to bring worry and fear to health officials and medical scientists, Centers for Disease Control and Prevention (CDC) and World Health Organization (WHO) have recommended that residents of the Zika-infected countries, e.g., Brazil, and those who have traveled to the area should delay having babies which may involve artificial contraceptive, particularly condom. This preventive policy, however, is seemingly at odds with the Roman Catholic Church’s position on the contraceptive. As least since the promulgation of (...) Paul VI’s 1968 encyclical, Humanae Vitae, the Church has explicitly condemned artificial birth control as intrinsic evil. However, the current pontiff, Pope Francis, during his recent visit to Latin America, remarked that the use of artificial contraception may not be in contradiction to the teaching of Humanae Vitae while drawing a parallel between the current Zika Crisis and the 1960’s Belgian Congo Nun Controversy. The pope mentioned that the traditional ethical principle of the lesser of two evils may be the doctrine that justified the exceptions. The authors of this paper attempt to expand the theological rationale of the pope’s suggestion. In so doing, the authors rely on casuistical reasoning as an analytic tool that compares the Belgian Congo Nun case and the given Zika case, and suggest that the former is highly similar to, if not the same as, the latter in terms of normative moral feature. That is, in both cases the use of artificial contraception is theologically justified in reference to the criteria that the doctrine of the lesser of two evils requires. The authors wish that the paper would provide a solid theological-ethical ground based on which condom-use as the most immediate and effective preventive measure can be recommended in numerous Catholic hospitals as well as among Catholic communities in the world, particularly the most Zika-affected and largest Catholic community in the world, Brazil – 123 million present Brazilian citizens are reported to be Roman Catholic.

Emily Chamlee-Wright is clearly right that self-censorship is an issue of concern within the academy. How much of a problem it is—how widespread and how bad it is when it occurs—is unclear and difficult to quantify. Administrators, faculty, and students all self-censor from time to time. Sometimes the self-censorship is just a matter of being polite or exercising pedagogical restraint, as Chamlee-Wright notes. The worry, of course, is that sometimes it prevents open and honest discussion about difficult topics (...) and thus stymies learning and truth-seeking. While I will keep these caveats in mind, I also want to help strengthen Chamlee-Wright’s case. I will also, though, point out a difficulty. (shrink)

This article presents a critical reevaluation of the thesis—closely associated with H. L. A. Hart, and central to the views of most recent legal philosophers—that the idea of state coercion is not logically essential to the definition of law. The author argues that even laws governing contracts must ultimately be understood as “commands of the sovereign, backed by force.” This follows in part from recognition that the “sovereign,” defined rigorously, at the highest level of abstraction, is that person or entity (...) identified by reference to game theory and the philosophical idea of “convention” as the source of signals with which the subject population has become effectively locked, as a group, into conformity.

1 Introduction1 In the 1980s, hermeneutics was often incorporated into deconstructionism and literary theory. Rather than focus on authorial intentions, the nature of writing itself including codes used to construct meaning, socio-economic contexts and inequalities of power,2 Gadamer introduced a different perspective; the interplay between effects of history on a reader’s understanding and the tradition(s) handed down in writing. This interplay in which a reader’s prejudices are called into question and modified by the text in a fusion of understanding and (...) topic revitalized the study of the printed word. Gadamer’s turn to language for understanding the meaning of Being also appealed to the post-modern antipathy toward modernity and metaphysics.3 If the truth and validity of interpretations are limited to communities of language, then our mode of being in history cannot but be historical. This point of view rendered Gadamer’s phenomenological hermeneutics vulnerable to the critique of moral and epistemological relativism. However, Gadamer’s theory of interpretation also stems from re-examination of the beginning of knowledge in the Pre-Socratics and Plato, and on this basis, is receptive to another dimension of inquiry than that which was trending in North America. -/- At the East-West Center, University of Hawai’i at Manoa in 1982, Chung-ying Cheng for the first time introduced onto-hermeneutics to an audience of esteemed philosophers including Li Zehou, Ren Jiyu, Feng Youlan, and Zhang Liwen.4 In contrast to schools of deconstruction and literary theory that had disengaged the interpreter from trans-historical sources of meaning and truth, Cheng explained that interpreters exist within a cosmological order inextricable from responsibility to harmonize Heaven and Earth in creative acts of interpretation. By integrating Chinese cosmology into hermeneutics through ontology, he tacitly challenged philosophers in the West to re-examine assumptions about humanity’s place in nature and by implication, Gadamer’s recovery of the beginnings of knowledge in Western philosophy. -/- Cheng’s Neo-Confucianism is inspired by the method and goals of Thomé H. Fang. The following words by Fang seem to prefigure, although in an indistinct and bundled way, aspects of Cheng’s philosophy including a Mencian theory of human nature, comprehensive observation, and creativity: “In the very process of living in concord with creative Nature, Man is charged with an ideal to be fully realized in the light of the principle of comprehensive harmony.”5 Like Fang, Cheng reinvigorates Chinese culture and language, but not solely in order to vindicate the insights of Neo-Confucianism. He has studied Western thought, from pragmatism and the analytic school to German idealism and phenomenology, to unlock and clarify philosophical concepts within the Yijing tradition and thereby render them intelligible to Anglophones. The result has been an awakening of Western scholars to the moral and cultural consequences of decoupling their thought from metaphysical foundations that are neither dogmatic nor doctrinal. -/- Not unlike the dialectic of Gadamer’s dialogue form, onto-generative hermeneutics integrates contrary positions on the same topic in order to blend both sides into a world philosophy, or as Cheng says, a “totalizing or integrative theory,”6 not to be confused with a theoretical rewording of a theory. On the contrary, the universal scope and relevance of hermeneutics stems from personal experience. Just as Gadamer, in response to faction and strife, immersed himself in Plato during the war years, and developed a method with which to harmonize opposites, so too, according to On-cho Ng, was Cheng moved by faction, strife and political persecution to develop a path toward unity.7 Gadamer taught at McMaster University in Hamilton, Ontario, and Cheng at the University of Hawai’i at Manoa among other institutions in North America. They facilitated trans-continental educational and cultural ties. Similar experiences yield similar insights irrespective of differences of time and place. Hence, authors in this issue who reside in Europe, China and North America, delineate the differences between Gadamer and Cheng, yet also, in light of Cheng’s onto-generative method and cosmology, develop integrative theories. Due to the page-budget restriction of the publisher, certain articles of this special theme will be subsequently published in the next issue. -/- 2 Integrative Theory This special issue of The Journal of Chinese Philosophy confirms a dimension of hermeneutics that Cheng has both motivated and inspired. The contributors do not abide by the conviction that since thought is mediated by language, interpretations cannot transcend culture. On the contrary, their research exemplifies the fruits of trans-historical onto-dialogical hermeneutics within limits defined by their field inquiry, organized into Parts I and II, around three themes: language, the philosophy of history and ethics. -/- Andrew Fuyarchuk introduces the theme of ontology in relation to Gadamer’s turn to language. Fuyarchuk argues that Chung-ying Cheng’s criticism of Gadamer’s hermeneutics is informed by Heidegger’s concept of Dasein and thereby overlooks how Gadamer’s Platonic-Pythagorean problem of the division between the One and Many is harmonized in the event of language, which in turn positions Gadamer in proximity to the presupposed grounds of receptivity in Cheng’s onto-generative hermeneutics. Lauren Pfister’s contributing article addresses the year 2000 meeting between Cheng and Gadamer in Heidelberg and expands the transhistorical grounds of meaning in Gadamer to matters of theology. Pfister’s summary of the written Chinese record of their conversation indicates that Cheng does not address the role of Christian philosophy and hence, the role of the inner word in Gadamer’s hermeneutics. This is important not only for detecting changes in Cheng’s philosophical development, but also for modifying his hermeneutics along the lines of a living conversation, possibilities explored by Pfister in a sequel to the article submitted to this issue. Nevertheless, by raising the issue of how Gadamer’s turn to language for understanding the meaning of Being extends possibilities in Cheng’s thought, Pfister anticipates the article by Katarina Gajdosova. She returns to the roots of Chinese thought during the Warring States period and broadens the meaning of names in recently excavated texts. Contrary to the conventions about how to understand terms, she appeals to both Heidegger’s ontology and Cheng’s notion of receptivity and creativity to reinterpret naming in relation to cosmology. Along the same lines, insofar as the event of Being is lingual, Jay Goulding captures its emergent structure in an evolving community of scholars and scholarship. He recalls his philosophical journey toward Cheng’s philosophy that begins in conversations with Gadamer at McMaster University in Hamilton, leads to Heidegger and Asian thought, expands into turning points with teachers and colleagues from various backgrounds that by increments contributed to Goulding’s formulation of “Daoist phenomenology.” -/- Although differing traditions guide their inquiries and research, Cheng and Gadamer recall the wisdom of the past to ameliorate the fragmentation in contemporary life. This leads them to re-examine the origins of philosophy; historical roots and thus sources of creative re-interpretations East and West whose affinities are developed in contributions by Hyun Höchsmann and Friederike Assandri. Höchsmann assesses convergences and divergences in the origins of Chinese and Western philosophy (Confucius and Socrates, the Yijing and Pre-Socratics) that culminates in pairing Gadamer’s understanding of paideia in the context of Plato’s political cosmology in the Timaeus with moral and social cultivation in The Western Inscription. She delineates the limits of this comparison which in turn justifies introducing Vattimo’s notion of locality. Assandri’s comparative analysis moves between India and China, Buddhism and Tang Daoism. Based on Gadamer’s argument that writing detaches concepts from their cultural moorings, she defines and applies three levels of understanding in onto-generative hermeneutics to Buddhist terms that were assimilated into the Benji Jing and in so doing clarifies essential dimensions of Daoism. -/- Contributions by Stephen Palmquist and Nicholas Brasovan position Cheng in relation to Kant and Gadamer by way of Aristotle’s ethics respectively. On the one hand, Palmquist plots Cheng’s evolving criticism of Kant’s moral philosophy and draws on crucial dimensions of Gadamer’s hermeneutics to reposition that criticism in a constructive relation to Kant’s emphasis on the philosophical conditions of morality while also indicating how religious dimensions of his thought answer Cheng’s concerns for lived moral action. For Palmquist, Gadamer enables a constructive criticism of Cheng. On the other hand, Brasovan compares Cheng’s Yijing-based account of moral deliberation with Gadamer’s Aristotelian-based ethics and reasons that in contrast to Cheng, Gadamer’s hermeneutical consciousness is disengaged from practical knowledge. For Brasovan, Cheng is a constructive critic of Gadamer. Palmquist and Brasovan’s divergent angles on Gadamer and Cheng map onto a dialectic of contrast and complementarity that constitutes the inner logic of Cheng’s philosophy. In other words, Gadamer and Cheng ought to be read alongside one another for the sake of removing discrepancies and contradictions, which constitutes the organic structure of their thinking. -/- 3 Our Mode of Being in History Is Not Historical The conversations between Cheng and Gadamer in this issue of The Journal of Chinese Philosophy pivot on language, philosophy of history and ethics within a comparative framework of analysis, but also explore the grounds that make the comparisons possible. Those grounds are informed by Chinese cosmology, and function to wrest Gadamer from the shadow of Heideggerian facticity and reposition him within the range of Cheng’s ideas about our place in nature that is embedded in his question about how mind emerges from inorganic matter.8 -/- For Gadamer scholars of Heidegger, human finitude, our ownmost individuating death ensures that hermeneutics is always open to the other as other, always on the way toward understanding the meaning of Being. To arrest the process in a concept of “the Absolute” cannot but represent someone’s point of view, and thereby render hermeneutics indistinguishable from ideology. However, insofar as finitude is defined by them in terms of an onto-theological concept of immorality, finitude is a metaphysical concept consistent with epistemologies and confuse beings with the meaning of Being. As a result, the celebrated political value of hermeneutics to always be on the way toward an understanding of the meaning of Being admits subtle variations on the same worldview that are insufficiently self-critical. -/- Gadamer scholars of Heidegger are right. A transformation in ethos and opening to the meaning of Being depends on awareness of finitude. Yet this awareness does not yield openness to more of the same, i.e., discourse structurally incapable of coming to unity but instead, for both Gadamer and Cheng, openness to a distinctly different ontological dimension of reality. As Sandra Wawrytko and So-Seong Park indicate,9 this ontological dimension is prefigured in the experience of being-as-a-whole or the totality of all possible relations in both Chinese totemic shamanistic rituals,10 and Greek Dionysian festivals.11 Through these religious experiences human ethos and therefore consciousness is expanded and elevated from being centered on one’s ownmost concerns toward an affinity with all sentient beings from insects and plants to animals. The channel for this affinity is an auditory disposition and hence, the emotions, compassion, and feeling response. -/- The capacity for an auditory disposition, or as Gadamer calls it, listening consciousness to respond to the inter-relationality and therefore inherent balance of nature is developed through music, song and dance of the religious rituals and festivals. They facilitate the unity of mind with nature. This use of music, that transforms ordinary consciousness, explains Cheng’s emphasis on the receptivity of feeling response in comprehensive observation, and Gadamer’s emphasis on openness to the other in attunement. However, an auditory disposition characteristic of pre-literate oral cultures that reveals the “All” need not rely on religion. As theorists about the evolution of language have explained,12 modern languages preserve their pre-historical past in music or prosody. That is to say, the song and dance that revealed the totality of inter-related beings to an ethos of comprehensive observation and attunement toward beings in classical civilizations is retained in the back-and-forth movement or rhythm of the dialogue form. Our mode of being in history is a mode of being in nature – through the music of language. -/- While alerting the reader to the limits of a nominalist interpretation, Gadamer expresses the inner law of the nature as follows: “in perishing there is always becoming, and in becoming there is always perishing.”13 Considered in process, opposites generate and blend into each other. This law of nature applies to everything.14 Hence, in a manner comparable to Pfister’s concluding insights, onto-dialogical hermeneutics is not only open to discrete events of otherness but moreover, to the moving structure of reality expressed, as Gajdosova suggests, in the existential moment of naming. Considered as interplay of tension and resolution with a life of its own, the dialectic of a dialogue is self-similar to the way in which an organism grows (by instinct). There is, therefore, a sense in which the art of interpretation extends the human mind into the eternal cycles of nature such that we participate in the articulation of the inner telos/homeostasis toward which all beings strive and importantly for Gadamer scholars of Heidegger, within the material limits of energy to which our embodied minds are self-evidently subject. In mortality there is always immortality. (shrink)

Putnam argues that reductionism, “the doctrine that the laws of such ‘higher level’ sciences as psychology and sociology are reducible to the laws of lower-level sciences - biology, chemistry, ultimately to the laws of elementary particle physics”, is wrong. In this note, I take issue with some of Putnam’s arguments.

Both short and long-term video-game play may result in superior performance on visual and attentional tasks. To further these findings, we compared the performance of experienced male video-game players (VGPs) and non-VGPs on a Simon-task. Experienced-VGPs began playing before the age of 10, had a minimum of 8 years of experience and a minimum play time of over 20 h per week over the past 6 months. Our results reveal a significantly reduced Simon-effect in experienced-VGPs relative to non-VGPs. However, this (...) was true only for the right-responses, which typically show a greater Simon-effect than left-responses. In addition, experienced-VGPs demonstrated significantly quicker reaction times and more balanced left-versus-right-hand performance than non-VGPs. Our results suggest that experienced-VGPs can resolve response-selection conflicts more rapidly for right-responses than non-VGPs, and this may in part be underpinned by improved bimanual motor control.

In Part I, an attempt is made to survey the original source material on which any detailed assessment of Wittgenstein's remarks on the foundations of mathematics from his middle and later periods ought to be based. This survey is presented within the context of a sketch of Wittgenstein's biography, which also mentions some of the major developments in his thinking. In addition, certain main themes are emphasized; these have to do primarily with the Kantian aspects of Wittgenstein's thought and with (...) his mysticism or the 'religious point of view'. In Part II, Kreisel's critique of Wittgenstein's remarks on the foundations of mathematics, which has been developed since 1958 in a series of published articles, receives close examination, and, in connection with this, different approaches to the philosophical investigation of mathematics are considered which represent genuine alternatives to Wittgenstein's approach. There are separate sections on Lakatos's Proofs and Refutations and Bourbaki's 'L'Architecture des Mathématiques'. Finally, besides a bibliography which surveys the reception of Wittgenstein's views on the foundations of mathematics, there are two substantial appendices, which are supplemental to Part I. The first of these gives the manuscript sources for typescripts 221 and 222-4, and the correspondences in both directions between these typescripts. The second appendix is part of a chronological version of von Wright's catalogue of Wittgenstein's papers, beginning in 1929. (shrink)

Scrutiny (1932-1953) was one of the most important critical reviews of the last century. Its editors and contributors included F. R. Leavis, Q. D. Leavis, Denys Thompson, L. C. Knights, D. W. Harding, W. H. Mellers, H. A. Mason, among others. In recasting Scrutiny’s critique of mass culture by way of Alisdair MacIntyre’s After Virtue (1981), I hope to show that the Scrutiny project not only dramatizes the conflicts internal to what MacIntyre calls emotivist culture, but provides a new way (...) of looking at the group’s relation to the culture industry, its purported elitism, and its deep ties with a communitarian rather than socialist politics.

Hoerl & McCormack posit two systems – the temporal updating system and the temporal reasoning system – and suggest that they explain an inherent contradiction in people's naïve theory of time. We suggest there is no contradiction. Something does, however, require explanation: the tension between certain sophisticated beliefs about time, and certain phenomenological states or beliefs about those phenomenological states. The temporal updating mechanism posited by H&M may contribute to this tension.

The National Library of Finland and the Von Wright and Wittgenstein Archives at the University of Helsinki keep the collected correspondence of Georg Henrik von Wright, Wittgenstein’s friend and successor at Cambridge and one of the three literary executors of Wittgenstein’s Nachlass. Among von Wright’s correspondence partners, Elizabeth Anscombe and Rush Rhees are of special interest to Wittgenstein scholars as the two other trustees of the Wittgenstein papers. Thus, von Wright’s collections held in Finland promise to (...) shed light on the context of decades of editorial work that made Wittgenstein’s later philosophy available to all interested readers. In this text, we present the letters which von Wright received from Anscombe and Rhees during the first nine months after Wittgenstein’s death. This correspondence provides a vivid picture of the literary executors as persons and of their developing relationships. The presented letters are beautiful examples of what the correspondence as a whole has to offer; it depicts – besides facts of editing – the story of three philosophers, whose conversing voices unfold the human aspects of inheriting Wittgenstein’s Nachlass. Their story does not only deal with editing the papers of an eminent philosopher, but with the attempt to do justice to the man they knew, to his philosophy and to his wishes for publication.

Donald Davidson established causalism, i.e. the view that reasons are causes and that action explanation is causal explanation, as the dominant view within contemporary action theory. According to his “master argument”, we must distinguish between reasons the agent merely has and reasons she has and which actually explain what she did, and the only, or at any rate the best, way to make the distinction is by saying that the reasons for which an agent acts are causes of her action. (...) “Davidson's challenge” to non‐causalists is to come up with an alternative, more convincing, way of drawing the distinction. In this paper, I argue that G.E.M. Anscombe and G.H. von Wright offer such an alternative. Moreover, I argue that Davidson's own account of interpretation makes no use of his causalist claim. (shrink)

Critical examination of Alchourrón and Bulygin’s set-theoretic definition of normative system shows that deductive closure is not an inevitable property. Following von Wright’s conjecture that axioms of standard deontic logic describe perfection-properties of a norm-set, a translation algorithm from the modal to the set-theoretic language is introduced. The translations reveal that the plausibility of metanormative principles rests on different grounds. Using a methodological approach that distinguishes the actor roles in a norm governed interaction, it has been shown that metanormative (...) principles are directed second-order obligations and, in particular, that the requirement related to deductive closure is directed to the norm-applier role rather than to the norm-giver role. The approach has been applied to the case of pure derogation yielding a new result, namely, that an independence property is a perfection-property of a norm-set in view of possible derogation. This paper in a polemical way touches upon several points raised by Kristan in his recent paper. (shrink)

H´ector-Neri Casta˜neda-Calder´on (December 13, 1924–September 7, 1991) was born in San Vicente Zacapa, Guatemala. He attended the Normal School for Boys in Guatemala City, later called the Military Normal School for Boys, from which he was expelled for refusing to fight a bully; the dramatic story, worthy of being filmed, is told in the “De Re” section of his autobiography, “Self-Profile” (1986). He then attended a normal school in Costa Rica, followed by studies in philosophy at the University of San (...) Carlos, Guatemala. He won a scholarship to the University of Minnesota, where he received his B.A. (1950), M.A. (1952), and Ph.D. (1954), all in philosophy. His dissertation, “The Logical Structure of Moral Reasoning”, was written under the direction of Wilfrid Sellars. He returned to teach in Guatemala, and then received a scholarship to study at Oxford University (1955–1956), after which he took a sabbatical-replacement position in philosophy at Duke University (1956). His first full-time academic appointment was at Wayne State University (1957– 1969), where he founded the philosophy journal Noˆus (1967, a counter-offer made to him by Wayne State to encourage him to stay there rather than to take the chairmanship of philosophy at the University of Pennsylvania). In 1969, he moved (along with several of his Wayne colleagues) to Indiana University, where he eventually became the Mahlon Powell Professor of Philosophy and, later, its first Dean of Latino Affairs (1978–1981). He remained at Indiana until his death. He was also a visiting professor of philosophy at the University of Texas at Austin (1962–1963) and a fellow at the Center for Advanced Study in the Behavioral Sciences (1981–1982). He received grants and fellowships from the Guggenheim Foundation (1967–1968), the T. Andrew Mellon Foundation, the National Endowment for the Humanities, and the National Science Foundation. He was elected President of the American Philosophical Association Central Division (1979– 1980), named to the American Academy of Arts and Sciences (1990), and received the Presidential Medal of Honor from the Government of Guatemala (1991). Casta˜neda’s philosophical interests spanned virtually the entire spectrum of philosophy, and his theories form a highly interconnected whole.. (shrink)

HISTÓRIA DA SOCIOLOGIA: O DESENVOLVIMENTO DA SOCIOLOGIA I -/- A SOCIOLOGIA NOS ESTADOS UNIDOS -/- -/- HISTORY OF SOCIOLOGY: THE DEVELOPMENT OF SOCIOLOGY I -/- SOCIOLOGY IN UNITED STATES -/- -/- Emanuel Isaque Cordeiro da Silva – IFPE-BJ, CAP-UFPE e UFRPE. E-mails: [email protected] e [email protected] WhatsApp: (82)9.8143-8399. -/- -/- PREMISSA -/- A Sociologia nos Estados Unidos desenvolveu-se no contexto de dois grandes eventos que marcaram profundamente a história do país. -/- O primeiro foi a Guerra de Secessão (também conhecida como (...) Guerra Civil Americana), que ocorreu entre 1861 e 1865 e gerou ressentimentos e atritos entre a população do sul e a do norte dos Estados Unidos. -/- Em contrapartida, houve a urbanização das terras do oeste e das áreas centrais do país, o que contribuiu para o crescimento da economia e a expansão industrial. No norte, graças ao esforço de guerra, houve um grande crescimento, principalmente na metalurgia, no transporte ferroviário, na indústria de armamentos e na indústria naval. O comércio também se expandiu de maneira exponencial em todo o território estadunidense. -/- O padrão de cultura dos Estados Unidos passou a ser o ideal nortista de “trabalho duro, educação e liberdade econômica a todos”. Houve ainda um grande desenvolvimento de escolas e instituições de ensino superior. -/- O segundo grande evento que marcou a história estadunidense foi a chegada em massa de estrangeiros. Entre 1860 e 1900, os Estados Unidos passaram de país agrícola, com população em torno de 4 milhões, para país industrial, com uma das maiores economias do mundo e com 75 milhões de habitantes. -/- O incremento populacional e a industrialização redundaram em um processo de urbanização sem precedentes que continuou até a década de 1930. Para se ter uma ideia, em 1860 viviam em Chicago 102 260 pessoas; em 1900, a população da cidade passou a 1 698 575 e, em 1930, a 3 375 329. Em virtude desses fatores, consolidaram-se nos Estados Unidos uma burguesia industrial, comercial e financeira significativa, uma classe trabalhadora majoritariamente formada por imigrantes e uma classe média em ascensão. -/- As principais cidades passaram a ser um espaço de conflito e alvo de preocupações. Temas como imigração, aculturação, conflitos étnicos, comportamentos desviantes e políticas públicas foram importantes na Sociologia desenvolvida inicialmente no país. -/- Entre os principais fundadores da Sociologia nos Estados Unidos estão William Graham Sumner (1840 -1910), Lester Frank Ward (1841-1913), Albion Woodbury Small (1854-1926), Franklin Henry Giddings (1855-1931), Thorstein Bunde Veblen (1857-1929), William Isaac Thomas (1863-1947), Robert Ezra Park (1864-1944), Charles Horton Cooley (1864-1929) e George Herbert Mead (1863-1931). -/- A herança cultural desses fundadores é muito diversa: foram influenciados principalmente pela tradição religiosa protestante disseminada em quase todo o território, pelo liberalismo econômico clássico conservador, do tipo laissez-faire, pelo evolucionismo do inglês Charles Darwin (1809-1882) e pelo darwinismo social de Herbert Spencer (1820-1903). Acrescente-se a esse cadinho de concepções de mundo e ciência o pragmatismo do filósofo e psicólogo William James (1842-1910) e do filósofo Charles Pierce (1839-1914). -/- Essa herança permite compreender as duas grandes características da Sociologia nos Estados Unidos: -/- • multiplicidade de temas, problemas e propostas e diversidade teórica e metodológica; -/- • desenvolvimento desse campo do conhecimento em universidades, nas quais as atividades eram financiadas pelo Estado e pelo setor privado (Fundação Rockefeller, comitês e associações normalmente religiosas). -/- Por causa dessa segunda característica, optei por analisar o desenvolvimento da Sociologia nos Estados Unidos em três importantes universidades estadunidenses: a de Chicago, Harvard e Columbia. -/- 1. A Universidade de Chicago -/- A Universidade de Chicago foi fundada em 1890 pelo magnata do petróleo John D. Rockefeller e recebeu os primeiros alunos em 1892. Nela foi criado o primeiro departamento de Sociologia dos Estados Unidos, sob a direção de Albion Woodbury Small. -/- No início de seus trabalhos sociológicos, a Universidade de Chicago deu primazia à pesquisa empírica, procurando conhecer, por meio da observação direta, a dinâmica das relações sociais. Desenvolveu uma forte tendência pragmática e microssociológica, que viria a ser conhecida como a Escola de Chicago. A maior preocupação dos integrantes dessa Escola foi com os problemas das grandes cidades dos Estados Unidos, como a marginalidade social, o alcoolismo, as drogas, a segregação racial e a delinquência, estabelecendo uma relação entre a pesquisa sociológica e a intervenção dos organismos públicos na sociedade. -/- Os sociólogos de Chicago também se dedicaram ao que chamaram de ecologia humana, em oposição à ecologia animal e vegetal. -/- Em 1895, Albion Woodbury Small fundou o American Journal of Sociology e, em 1907, participou ativamente da fundação da Sociedade Americana de Sociologia. Ele publicou, com Georges Vincent, em 1894, talvez o primeiro manual de Sociologia para estudantes, intitulado Introdução ao estudo da sociedade. Tendo estudado na Alemanha, Small foi o principal divulgador do pensamento de Georg Simmel nos Estados Unidos. -/- Entre os integrantes da Escola de Chicago mais conhecidos no Brasil, podemos citar William I. Thomas (1863-1947) e Florian Znaniecki (1882-1958), cuja principal obra foi O camponês polonês na Europa e na América, editada em 1918. -/- Destacam-se ainda Robert E. Park (1864-1944) e Ernest W. Burgess (1886-1966), que escreveram, entre outras obras, Introdução à ciência da Sociologia, em 1921. -/- Os dois, com Roderick Mackenzie, escreveram o clássico A cidade, em 1925. Outro membro de destaque foi Louis Wirth (1897-1952), autor de O gueto, escrito em 1928, e de um artigo que se tornou famoso, “Urbanismo como modo de vida”, publicado em 1938, no American Journal of Sociology. -/- A Escola de Chicago congregou, ainda, sociólogos e antropólogos com ligação com a Psicologia Social, que desenvolveram uma abordagem sociológica das relações sociais conhecida como interacionismo simbólico. A principal figura dessa vertente foi George Herbert Mead (1863-1932), que trabalhou em diversas áreas, sobretudo como psicólogo social e como professor de várias gerações de antropólogos e sociólogos. Seus escritos foram sistematizados por seus alunos e publicados com o nome Mind, self and society (A mente, o eu e a sociedade), em 1934. -/- Além da tradição intelectual dos Estados Unidos, os integrantes da Escola de Chicago receberam a influência de Jean-Gabriel de Tarde, Émile Durkheim e Georg Simmel. Seus continuadores foram Herbert Blumer (1900-1987) e Everett C. Hughes (1897-1983). -/- 1.1 Erving Goffman (1922-1982) -/- O representante da Sociologia desenvolvida na Universidade de Chicago mais influente no Brasil é Erving Goffman, que nasceu em Manville, Alberta, no Canadá, em 1922, e faleceu nos Estados Unidos em 1982. Obteve o grau de bacharel pela Universidade de Toronto, em 1945, e concluiu mestrado (1949) e doutorado (1953) na Universidade de Chicago, onde estudou Sociologia e Antropologia Social. Em 1958, tornou-se professor da Universidade da Califórnia e, em 1968, ingressou na Universidade da Pensilvânia, onde foi professor de Antropologia e Sociologia. -/- Entre 1981 e 1982, Goffman foi presidente da Sociedade Americana de Sociologia e realizou pesquisas na linha da Sociologia interpretativa e cultural, iniciada por Max Weber, desenvolvendo a ideia de que o mundo é um teatro e cada um, individualmente ou em grupo, interpreta papéis de acordo com as circunstâncias em que se encontra. Essas circunstâncias são marcadas por rituais e posições distintivas em relação a outros indivíduos ou grupos. Para ele, é possível distinguir indivíduos, grupos e classes com base, por exemplo, em aspectos como as formas de vestir ou de se apresentar publicamente. -/- O sociólogo considera a interação social como um processo fundamental de identificação e de diferenciação dos indivíduos e grupos, analisando-a no cotidiano, especialmente em lugares públicos. Goffman estudou com especial atenção o que chamou de “instituições totais”, lugares onde o indivíduo é isolado da sociedade, como prisões e manicômios. -/- De acordo com o sociólogo brasileiro Édison Gastaldo: -/- O trabalho de Goffman trouxe à luz aspectos da vida cotidiana que não se julgavam “sociologicamente relevantes”. Seus insights sobre as interações ordinárias, sobre o deslocamento dos pedestres, sobre a ocupação social dos espaços públicos, sobre a atuação dos vigaristas, mendigos, loucos, espiões, jogadores e de todos aqueles que passam cotidianamente debaixo de nossos narizes sem que prestemos atenção modificaram o pensar sociológico no mundo. Sua descrição etnográfica de um hospital para doentes mentais colaborou decisivamente para deflagrar a luta antimanicomial no mundo inteiro. Vinte e dois anos depois de sua morte, os temas e os conceitos desenvolvidos por Goffman ainda estão em pleno uso e vitalidade (GASTALDO, 2004, p. 9/10). -/- Suas três obras mais conhecidas são: A representação do eu na vida cotidiana (1959), Manicômios, prisões e conventos (1961) e Estigma: notas sobre a manipulação da identidade (1963). -/- 2. A Universidade Harvard -/- A história de Harvard começa em 1636, quando foi fundada, na cidade de Cambridge, no estado de Massachusetts, uma instituição de ensino denominada New College. Em 1639, essa instituição recebeu o nome de Harvard College, em homenagem a John Harvard, seu principal mecenas. -/- A Sociologia desenvolvida na Universidade Harvard é marcada por uma preocupação teórica e tem dois sociólogos como expoentes: Pitirim Alexandrovich Sorokin (1889-1968) e Talcott Edgar Frederick Parsons (1902-1979). Este último influenciou muito o desenvolvimento da Sociologia no mundo e no Brasil. -/- 2.1 Talcott Parsons (1902-1979) -/- Talcott Parsons nasceu no Colorado, nos Estados Unidos. Em 1924, graduou-se em Biologia e Filosofia na Faculdade Amherst. Em 1925, pós-graduou-se em Ciências Sociais na Escola de Economia de Londres, na Inglaterra, e, em seguida, doutorou-se na Universidade de Heidelberg, na Alemanha. -/- Nos Estados Unidos, lecionou Economia e Sociologia na Universidade Harvard durante 45 anos (1927-1973). Em 1944, tornou-se presidente do Departamento de Sociologia, transformando-o, dois anos depois, no Departamento de Relações Sociais, a fim de unir a Sociologia a outras ciências sociais. -/- Assim como Sorokin, Parsons voltou-se para a Sociologia europeia, tendo por base as ideias de Max Weber, Vilfredo Pareto (1848-1923) e Émile Durkheim, além das do economista inglês Alfred Marshall (1842-1924). Fundamentado nesses autores, desenvolveu uma grande obra teórica, que dominaria a Sociologia estadunidense desde então. -/- Parsons é o sociólogo estadunidense mais conhecido no mundo. Em geral, seus críticos entenderam-no como um pensador conservador, preocupado basicamente com o bom ordenamento da sociedade. Seu interesse era determinar a função que os indivíduos desempenhavam na estrutura social. Entendia o indivíduo como expressão dessa estrutura, a qual devia ser mantida e preservada. Caso isso não ocorresse, deviam entrar em ação os mecanismos de controle social (moral, ética, sistema jurídico e penal etc.), como instrumentos preventivos ou corretivos. -/- Seu trabalho exerceu influência em diversos países e ambientes acadêmicos (particularmente nas décadas de 1950 a 1970), até mesmo na então União Soviética, onde, em 1964, ministrou aulas sobre a Sociologia estadunidense a convite da Academia de Ciências da União Soviética (URSS). -/- Suas principais obras foram: A estrutura da ação social (1937), O sistema social (1951), Economia e sociedade (1956, com N. Smelser), Estrutura e processo nas sociedades modernas (1960), Sociedades: perspectivas evolucionárias e comparativas (1966), Teoria sociológica e sociedade moderna (1968), Política e estrutura social (1969), Sistemas sociais e a evolução da teoria da ação (1977) e Teoria da ação e a condição humana (1978). -/- 3. A Universidade Columbia -/- A King’s College foi fundada em 1754, em Nova York, nos Estados Unidos. Quando as colônias inglesas se declararam independentes da Grã-Bretanha, a instituição passou a se chamar Universidade Columbia. A partir da última década do século XIX, essa universidade se destacaria por uma importante produção no campo da Sociologia, tendo como pioneiro Franklin Giddings (1855-1931), fundador da cadeira de Sociologia. Fortemente marcado pelo evolucionismo e pelo pragmatismo, foi um dos primeiros a usar métodos quantitativos e experi-mentais no estudo dos fenômenos sociais. -/- Dois sociólogos de Columbia merecem destaque, por serem muito conhecidos no Brasil: Robert K. Merton e Charles Wright Mills. -/- 3.1 Robert King Merton (1910-2003) -/- Merton nasceu na Filadélfia e faleceu em Nova York. Graduou-se em Sociologia na Universidade Temple e pós-graduou-se na Universidade Harvard, onde trabalhou com Pitirim Sorokin e Talcott Parsons até a defesa de seu doutorado, em 1936. -/- Em 1941 Merton transferiu-se para a Universidade Columbia, onde permaneceu durante 38 anos, até aposentar-se. Nessa universidade procurou integrar teoria à prática sociológica. Estudou o comportamento desviante e os processos de adaptação social, tendo por base pesquisas qualitativas e quantitativas do exercício profissional em ambiente de solidariedade e de conflito. Com Paul Lazarsfeld (1901-1976), desenvolveu o Departamento de Pesquisa Social Aplicada. -/- O nome de Merton está vinculado à proposta de criação de teorias de alcance médio, segundo a qual os sociólogos seriam mais úteis à sociedade se deixassem de lado as grandes teorias (criticando Parsons) e criassem outras de médio alcance. Essas teorias estariam situadas entre as hipóteses de trabalho rotineiras na pesquisa e as amplas especulações. Mediariam, dessa forma, as abstrações, generalizações e fundamentos empíricos da pesquisa. -/- Merton tinha uma visão humanista da função social da ciência, demonstrando influência clara de Max Weber. Concebia a ciência como um conjunto de conhecimentos compartilhados por todos os membros da sociedade, que deveriam julgar a credibilidade das postulações científicas de acordo com suas expectativas e valores morais. Mas as decisões acerca do fazer científico não caberiam à sociedade, e sim ao próprio cientista, sempre adequando seus valores aos da sociedade. -/- 3.2 Charles Wright Mills (1916-1962) -/- Charles Wright Mills (1916-1962) nasceu em Waco, no Texas, Estados Unidos. Mestre em Artes, Filosofia e Sociologia pela Universidade do Texas, concluiu, em 1942, seu doutorado em Sociologia e Antropologia pela Universidade de Wisconsin. Foi professor de Sociologia nas universidades de Maryland e Columbia, onde passou a lecionar em 1947 e permaneceu até a morte, em 1962. -/- Charles Mills representa uma tendência quase marginal na Sociologia dos Estados Unidos, por apresentar uma visão crítica e militante da sociedade estadunidense e da própria Sociologia. -/- Influenciado por Karl Marx e Max Weber, Mills procurou conciliar o conceito de classe social com o de status, visando esclarecer processos e mecanismos dos conflitos e das mudanças sociais. Por meio de pesquisas, tentou elucidar a complexidade de estruturas de poder, particularmente das elites (em lugar de classes dominantes), e de seu papel na mudança social, fugindo da ideia de revolução como única via para a transformação social. -/- Charles Wright Mills é conhecido principalmente por seu livro A imaginação sociológica, publicado originalmente nos Estados Unidos em 1959. Nele, o autor propõe que os sociólogos, ao exercer a profissão, não deixem a imaginação e a criatividade de lado em favor de uma pretensa objetividade e neutralidade do trabalho científico. Para Mills, os grandes intelectuais da história nunca abriram mão da reflexão e da criatividade e mantiveram uma postura crítica diante da realidade. -/- Atribuindo aos sociólogos a responsabilidade de agentes ativos na sociedade, cabendo-lhes tomar parte nos debates públicos de sua época, Mills defendia a ideia de que a Sociologia deveria ser compreensível para o grande público. Para ele, a ciência social era inseparável da vida pessoal do cientista: a intuição, a imaginação e o comprometimento com o tempo em que se vivia eram fundamentais para compreender cientificamente a sociedade. Suas obras foram publicadas em vários idiomas. Além da citada anteriormente, as mais importantes são: A nova classe média (1951), A elite do poder (1956), Sobre o artesanato intelectual (1959) e Os marxistas (1962). -/- Mills escreveu também artigos em revistas e dois livros que tiveram grande exposição na mídia dos Estados Unidos, por seu caráter polêmico: As causas da Terceira Guerra Mundial (1958), no qual discute a corrida nuclear, e A Revolução em Cuba (1960), em que analisa a fase inicial da Revolução Cubana. -/- Outros sociólogos que defendem uma postura crítica na Sociologia estadunidense, continuadores ou não de Charles Wright Mills, são Irving Louis Horowitz (1929-2012), Martin Nicolaus (1928-) e Alvin Gouldner (1920-1980). -/- REFERENCIAL TEÓRICO -/- BOTTOMORE, T.; et al.

TRANSPORTE DE GAMETAS, FERTILIZAÇÃO E SEGMENTAÇÃO -/- • _____OBJETIVO -/- O entendimento do desenvolvimento embrionário nos estágios iniciais, desde a deposição dos espermatozoides na fêmea, passando pela fertilização deste no ovócito e na formação do zigoto, é de suma importância para diferenciar especialistas em reprodução e manejo reprodutivo no mercado de trabalho e, também, durante a vida acadêmica. Compreender os processos que levam à formação do zigoto na fêmea é essencial para avaliar a capacidade reprodutiva dos animais e, mediante técnicas, (...) avaliar o trato reprodutivo da fêmea e o desenvolvimento do embrião até a formação do feto e, por fim, em um novo animal sadio na propriedade. Com esse trabalho, o estudante de veterinária ou zootecnia, que deseja se aprofundar na fisiologia da reprodução animal, identificará os mecanismos que são envolvidos no transporte dos gametas, bem como os processos que estes últimos devem completar para alcançar a fertilização e para desencadear as divisões iniciais do embrião. -/- • _____INTRODUÇÃO -/- A fertilização ou fecundação é o processo pelo qual os gametas masculino (espermatozoide) e feminino (ovócito) se fundem para gerar um novo indivíduo. Seu êxito depende da culminação adequada dos diferentes processos que devem sofrer os gametas durante sua maduração e percurso; do transporte oportuno destes no trato reprodutivo da fêmea, assim como de uma série de adaptações dos órgãos genitais internos da mãe. A segmentação refere-se às primeiras divisões celulares do embrião. -/- • _____TRANSPORTE DO OVÓCITO -/- O ovócito que é liberado na ovulação, e que se encontra coberto pelas células do cumulus (figura 1), é capturado pela fímbria do infundíbulo ao aderir aos cílios. Esse processo é altamente eficaz, inclusive em espécies onde os ovários possuem várias formações globosas, por exemplo nas porcas, onde os ovidutos capturam entre 95 e 100% dos ovócitos que são ovulados. As contrações das camadas musculares do oviduto e o movimento intenso dos cílios da mucosa faz com que as secreções fluam em direção ao útero, transportando assim o complexo cumulus-ovócito. Esse transporte é relativamente rápido até alcançar a junção da ampola com o istmo (que é considerado o local de fertilização do espermatozoide e ovócito) a partir do qual se torna lento. Devido a fêmea estar em estro, o processo está sob controle endócrino, isto é, controle hormonal através do estradiol. Nas fêmeas domésticas, ao contrário das mulheres, o transporte ao longo do oviduto é extremamente eficiente, pois os embriões passam para o útero sem dificuldade, de modo que gestações ectópicas (tubárias ou em cavidade) são quase inexistentes. A égua, frequentemente, retém por muito tempo os ovócitos não fertilizados no oviduto, provavelmente devido a não secreção de substâncias (como a prostaglandina E) que poderiam favorecer sua passagem, como se propõe que aconteça com os embriões. A figura 2 apresenta um ovócito com suas respectivas estruturas. Figura 1: ovócitos de uma vaca madurados in vitro. Nota-se as células do cumulus que os recobre. -/- Figura 2: estruturas do ovócito de uma ovelha que se encontra na etapa de ovócito secundário, depois da ovulação. Elaborado pelo autor. • _____TRANSPORTE ESPERMÁTICO -/- Para que os espermatozoides sejam capazes de fertilizar o ovócito, deverão sofrer uma série de mudanças bioquímicas e morfológicas ao longo de sua passagem pelo aparelho reprodutor tanto masculino como feminino. Uma vez produzidos na parede do túbulo seminífero, os espermatozoides são liberados em direção ao lúmen tubular e transportados passivamente para uma estrutura ramificada conhecida como rede testicular (rete testis). Dessa rede são conduzidos em direção ao epidídimo passando através de 10 a 20 ductos eferentes localizados no polo superior do testículo. O epidídimo é dividido em três seções denominadas cabeça, corpo e cauda; é constituído por um só ducto longo e tortuoso que continua com o canal deferente. Ao final desemboca nas ampolas seminais, no ducto ejaculatório e na uretra. As funções do epidídimo são as de maduração, transporte e armazenamento dos espermatozoides. O transporte através do epidídimo é lento, aproximadamente de 10 dias em touros, e segue sendo passivo. Os espermatozoides tomados da cabeça do epidídimo são ainda imaturos e incapazes de fertilizar, enquanto os armazenados na cauda são completamente maduros. Durante o trânsito pelo epidídimo os espermatozoides adquirem motilidade e o potencial para fertilizar, o acrossomo é remodelado e a gota citoplasmática migra para o flagelo e é liberada. Quando um macho ejacula com muita frequência, é possível observar espermatozoides com gota citoplasmática no sêmen, já que não há tempo suficiente para que completem sua maduração. Os espermatozoides são expulsados fora do organismo durante a cópula, na masturbação ou em emissões espontâneas. Na ejaculação, os espermatozoides que se encontram suspensos nos fluidos do testículo e do epidídimo, misturam-se ao chegar na uretra com as secreções das glândulas acessórias para formar o sêmen. Essas secreções denominadas plasma seminal, proporcionam substâncias para manter o metabolismo energético das células espermáticas, e integram suas membranas elementos que impedem uma capacitação prematura. Durante a cópula, o sêmen é depositado na vagina ou no útero, variando entre as espécies (tabela 1). Na monta natural, geralmente, o serviço ocorre no momento propício, já que está definido pela fase do ciclo estral em que a fêmea é receptiva ao macho. No entanto, na inseminação artificial, é o macho que deverá determinar o momento ideal, e para isso é importante considerar a vida média dos gametas, ao qual é muito curta no caso dos ovócitos (tabela 1). -/- Tabela 1: local de depósito do sêmen, volume da ejaculação e vida média dos gametas. Espécie Local de deposição Volume (ml) Velocidade de ejaculação Vida média do ovócito Vida média do espermatozoide Bovinos Intravaginal 2 1 – 3 seg 8 h 30 – 48 h Caninos Intravaginal 2 – 30 (10 média) 6 – 45 min 48 – 72 h 9 – 11 d Equinos Intrauterina 50 – 200 20 – 60 seg 6 – 8 h 72 – 120 h Humanos Intravaginal 3 - - 5 – 6 d Ovinos Intravaginal 1 1 – 2 seg 16 – 24 h 30 – 48 h Suínos Intrauterina 200 – 400 5 – 20 min 8 – 10 h 24 – 48 h Onde d = dias; h = horas. A vida fértil do ovócito é muito curta, portanto, o momento do serviço é de grande importância para obter altos índices de fertilização. -/- Independentemente do local em que os espermatozoides sejam depositados no aparelho reprodutor feminino, serão expostos às secreções genitais e sofrem uma série de mudanças em seu trajeto até o local de fertilização antes de penetrar no ovócito. Nas espécies em que o sêmen é depositado na parte cranial da vagina, uma parte do mesmo penetra através da cérvix, enquanto outra parte é eliminada do aparelho genital da fêmea, em pouco tempo, através do fluxo retrógrado. O meio vaginal não é adequado e imobiliza os espermatozoides em pouco tempo, pelo qual deverão entrar no útero onde o ambiente é mais propício. O transporte espermático na fêmea é o resultado da alta contratilidade, do movimento ciliar e o fluido do aparelho genital durante o estro, ao qual está sob controle endócrino e do sistema nervoso. Esse transporte é favorecido pelas características especiais do muco estral, cujas moléculas formam uma espécie de canais que facilitam a passagem dos espermatozoides. Pelo contrário, durante a fase lútea seu transporte é dificultado. Além do meio vaginal, a cérvix também atua como barreira natural para limitar a passagem dos espermatozoides, diminuindo assim a possibilidade de polispermia. Funciona, também, como um filtro que seleciona os espermatozoides aptos dos que não o são, uma vez que somente os primeiros possuem uma motilidade vigorosa que lhes permite passar pelo muco altamente hidratado. Na vaca a cérvix é considerada como um reservatório espermático. Quando atravessam a cérvix, os espermatozoides seguem sua deslocação tanto por movimento próprio como pelas contrações uterinas e tubárias. Nas espécies em que o local de depósito do sêmen do macho na fêmea é intrauterino, como equinos, a principal barreira que os espermatozoides enfrentam é a união ou junção útero-tubárica. A união entre o útero e o oviduto (istmo do oviduto) serve como reservatório funcional dos espermatozoides nas espécies domésticas. Poucos minutos depois da cópula, é possível encontrar alguns espermatozoides no oviduto, que é conhecido como fase de transporte rápido. No entanto, esses espermato-zoides não são os que participam do processo de fertilização e podem apresentar certas anormalidades. Existe um segundo tipo de transporte denominado fase sustentada, a qual consiste na migração prolongada dos espermatozoides em direção as partes mais craniais do aparelho genital feminino, que conduzem à colonização do reservatório funcional e na liberação gradual dos espermatozoides dos reservatórios espermáticos, incluindo este último. O reservatório do istmo fornece aos espermatozoides um ambiente propício, protegendo-os contra a fagocitose, prolongando assim a sua viabilidade. Aqui os esper-matozoides permanecem aderidos a superfície das células ciliadas do epitélio até a finalização de sua capacitação, depois da qual são liberados quando alteram seu padrão de motilidade flagelada, fenômeno conhecido como hipermotilidade, e migram em ondas em direção ao local da fertilização. Dos milhões de espermatozoides ejaculados, somente alguns milhares alcançarão o istmo do oviduto e um número sumamente pequeno será encontrado nas imediações do ovócito no momento da fertilização. -/- • _____CAPACITAÇÃO ESPERMÁTICA E REAÇÃO ACROSSÔMICA -/- A capacitação é um processo gradual e essencial para a fertilização. Os espermato-zoides devem passar por um dado tempo de “incubação” no aparelho genital da fêmea e sofrer uma série de mudanças antes de serem capazes de fecundar o ovócito. A capacita-ção dos espermatozoides começa quando eles entram em contato com as secreções do aparelho genital da fêmea e termina no istmo do oviduto. Durante esse percurso a superfície da cabeça do espermatozoide se modifica já que algumas moléculas como o colesterol são removidas da membrana plasmática, aumentando sua fluidez e alterando suas propriedades bioquímicas. Entre outras coisas, essa reorganização dos lipídios facilita a entrada de cálcio extracelular pelos canais iônicos e ocasiona a desestabilização da membrana, tornando-a mais fusogênica. Também são eliminados outros fatores (conhecidos genericamente como fatores descapacitantes) que expõem receptores membranais indispensáveis para a realização da união entre o espermatozoide e o ovócito durante a fertilização. Os espermatozoides capacitados apresentam um padrão de hipermotilidade e uma maior atividade metabólica, características que devem obter para que sejam capazes de penetrar as camadas do ovócito. A capacitação é necessária para que ocorra a reação acrossômica. A reação acrossomal ou acrossômica (RA) é um fenômeno de exocitose que é desencadeada pela ligação entre as proteínas e receptores localizados na membrana do espermatozoide e a zona pelúcida do ovócito (figura 3). Envolve a fusão da membrana plasmática do espermatozoide com a membrana externa de seu acrossomo; formando, assim, pequenas vesículas, cujo conteúdo de enzimas hidrolíticas, como a hialuronidase e a acrosina, é liberado em direção ao seu exterior, facilitando a penetração da zona pelúcida. A adesão do espermatozoide à zona pelúcida é específica da espécie e depende de glicoproteínas presentes na membrana dos ovócitos maduros; a cabeça do espermatozoide se une com essas glicoproteínas mediante receptores específicos e atravessam em direção oblíqua a zona pelúcida até chegar ao espaço perivitelino. Nos mamíferos, particularmente em roedores e nos humanos, algumas dessas glicoproteínas são conhecidas como ZP1, ZP2 e ZP3. Pensa-se que a união da membrana espermática a esta última é o que desencadeia a reação acrossomal. Posteriormente, as vilosidades do ovócito entram em contato com o espermatozoide e a membrana presente na secreção equatorial da cabeça do espermatozoide, que tem proteínas fusogênicas específicas, une-se a membrana plasmática do ovócito, fusionando-se e permitindo a entrada do núcleo espermático ao citoplasma (figura 4). A capacitação dos espermatozoides é fundamental para o êxito da fertilização, uma vez que apenas os aptos estarão perfeitos e íntegros para que a união e percepção das glicoproteínas presentes nos mesmos possam ocorrer de forma ideal para a penetração deste no ovócito, fertilizá-lo e formar um zigoto. Figura 3: estrutura do espermatozoide. Nota: a membrana é acrossomal e não acrossonal. Elaborado pelo autor. -/- Figura 4: eventos que ocorrem durante a fertilização. A – depois de passar através das células do cumulus, o espermatozoide entra em contato com a zona pelúcida, onde receptores da membrana plasmática reconhecem as proteínas da zona pelúcida; B – é desencadeada, então, a reação acrossomal; C – para que o espermatozoide penetre na zona pelúcida; D – ao atravessar a zona pelúcida e entrar no espaço perivitelino, a cabeça do espermatozoide entra em contato com a membrana vitelina; ambas membranas se fusionam graças ao reconhecimento de proteínas fusogênicas que estão no segmento equatorial. E – ocorre, então, que o núcleo do espermatozoide penetra no citoplasma do ovócito; uma das consequências da fusão da membrana com a cabeça do espermatozoide é a reação cortical, em que os grânulos corticais do ovócito liberam seu conteúdo em direção ao espaço perivitelino, o que resulta na alteração da estrutura da zona pelúcida e da membrana vitelina para bloquear a polispermia. Elaborado pelo autor. • _____CONSEQUÊNCIAS DA PENETRAÇÃO -/- Bloqueio da polispermia -/- A fusão das membranas dos gametas durante a penetração permite a entrada da fosfolipase C zeta (PLCζ) – fator solúvel que provém do espermatozoide – que desencadeia liberação e oscilações de Ca2+ no retículo endoplasmático. Isso, por sua vez, provoca a migração e fusão dos grânulos corticais, com a consequente liberação de enzimas, que mudam tanto a estrutura da zona pelúcida (por exemplo a inativação de ZP3), como a da membrana vitelina. Desse modo, impede-se que outros espermatozoides as penetrem, evitando assim a polispermia (figura 5). -/- Figura 5: os grânulos corticais que encontram-se na periferia do citoplasma, debaixo da superfície da membrana do ovócito, migram e fusionam-se sobre a mesma, liberando seu conteúdo no espaço perivitelino imediatamente depois da penetração do espermatozoide. A – como conse-quência, tanto a membrana vitelina como a zona pelúcida são modificadas, impedindo a entrada de mais espermatozoides, o que evita a polispermia. B – o ovócito retoma, então, sua segunda divisão meiótica, que ocasiona a expulsão do segundo corpúsculo polar, e na formação dos pronúcleos feminino e masculino. C – continuando, os pronúcleos migram, suas membranas se dissolvem e os cromossomos de ambos se condensam e se unem. Completa-se, assim, a singamia e forma-se, então, o zigoto. Elaborado pelo autor baseado nos livros de embriologia e fisiologia da reprodução conforme vida bibliografia. -/- Ativação do ovócito e formação de pronúcleos -/- Na maioria das fêmeas domésticas, com exceção da cadela, o ovócito encontra-se suspenso na metáfase II da segunda meiose no momento da ovulação. A entrada da PLCζ do espermatozoide no citoplasma do ovócito, e a consequente liberação de Ca2+, faz com que o ovócito se ative, terminando a segunda divisão meiótica e expulse o segundo corpo polar. Posteriormente, o material nuclear do ovócito se reorganiza para formar o pronú-cleo feminino. Entretanto, a membrana nuclear do espermatozoide se dissolve, a cromatina descondensa-se, as protaminas são substituídas por histonas, e se forma uma nova membrana nuclear, dando lugar ao pronúcleo masculino. -/- Singamia -/- Uma vez que os pronúcleos feminino e masculino são formados, migram para o centro do ovócito, aproximam-se, suas membranas se dispersam e os cromossomos paternos e maternos se associam, com o qual recupera a condição diploide e dá origem ao zigoto (figura 5). -/- • _____DESENVOLVIMENTO EMBRIONÁRIO -/- Poucas horas após a fertilização ocorre a primeira divisão do zigoto em duas, depois em 4, 8, 16 e 32 células, denominadas blastômeros. Essas divisões mitóticas são conhecidas como divisões de segmentação ou clivagem (figura 6), uma vez que são realizadas sem aumento do citoplasma, de modo que com cada divisão os blastômeros se tornam menores. A partir das 16 células o embrião se chama mórula, e é visto como uma massa celular compacta. A compactação deve-se a informação de proteínas de ligação entre os blastômeros. O embrião acumula líquido em seu interior, formando uma cavidade denominada blastocele. Esse processo é conhecido como blastulação; o embrião, assim, passa a ser chamado de blastocisto. Nessa etapa é possível diferenciar duas populações de células embrionárias: a massa celular interna, embrioblasto ou botão embrionário (que dará origem ao embrião), e a massa celular externa, células superficiais ou trofoblasto, do qual se originam a maioria das membranas fetais. Ao continuar a multiplicação das células e a acumulação de líquido, o blastocisto aumenta de tamanho, convertendo-se em blastocisto expandido. A zona pelúcida torna-se mais fina e, finalmente, o embrião eclode; isto é, o embrião é liberado da zona pelúcida. -/- • _____FERTILIZAÇÕES ATÍPICAS -/- Polispermia -/- É a penetração de dois ou mais espermatozoides no óvulo. Esta condição é letal nos mamíferos, já que o número cromossômico desse zigoto é maior que 2n, o envelheci-mento do ovócito da porca, como consequência do serviço tardio, favorece a apresentação da polispermia, por isso, é comum ver números de nascimentos de média de 10 a 12 leitões por parição nessa espécie. Nas aves, no entanto, a penetração de mais de um espermatozoide é normal, embora apenas um pronúcleo masculino se formará, fundindo-se com o feminino. -/- Figura 6: etapas do processo de segmentação/clivagem. Fonte: aula de reprodução da professora Domenica Palomaris, UFT. -/- Ginogênese -/- É o desenvolvimento de um embrião a partir de um óvulo normal fecundado por um espermatozoide, mas sem a fusão dos cromossomos masculinos com os da fêmea. A função do espermatozoide, nesse caso, é a de ativação do ovócito para que este inicie seu desenvolvimento, mas não há fusão com o núcleo do espermatozoide. Ocorre em plantas, em nematódeos e em algumas espécies de peixes, por exemplo a Poecilia formosa, espécie em que os ovócitos das fêmeas são ativados por machos de outra espécie relacio-nada. -/- Partenogênese -/- Consiste no desenvolvimento do embrião sem a participação do espermatozoide. Ocorre em alguns insetos, o zangão, por exemplo, é partenogenético. Também pode apresentar-se em perus, cujos embriões são machos e, geralmente, morrem antes da eclosão. -/- • _____GÊMEOS -/- Existem dois tipos de gêmeos: idênticos ou monozigóticos e os não idênticos ou dizigóticos. -/- Idênticos ou monozigóticos -/- Originam-se do mesmo zigoto, sendo assim, possuem o mesmo genótipo e um fenótipo similar e, portanto, são do mesmo sexo. Em laboratório é possível gerá-los ao seccionar uma mórula em duas ou mais partes, por meio de um micromanipulador. Uma vez que possuem o mesmo genótipo, os produtos resultantes são clones. -/- Não idênticos ou dizigóticos -/- Provêm da fertilização de dois óvulos distintos por espermatozoides diferentes. Possuem, portanto, genótipos e fenótipos diferentes, e podem ser de sexo diferente. -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- ALBERTS, Bruce et al. Biologia molecular da célula. Artmed Editora, 2010.

The present volume is a sequel to Deontic Logic: Introductory and Systematic Readings : its purpose is to offer a view of some of the main directions of research in contemporary deontic logic. Most of the articles included in Introductory and Systematic Readings represent what may be called the standard modal approach to deontic logic, in which de on tic logic is treated as a branch of modal logic, and the normative concepts of obligation, permission and prohibition are regarded as (...) analogous to the "alethic" modalities necessity, possibility and impossibility. As Simo Knuuttila shows in his contribution to the present volume, this approach goes back to late medieval philosophy. Several 14th century philosophers observed the analogies between deontic and alethic modalities and discussed the deontic interpretations of various laws of modal logic. In contemporary deontic logic the modal approach was revived by G. H. von Wright's classic paper 'Deontic Logic'. Certain analogies between deontic and alethic modalities are obvious and uncontroversial, but the standard approach has often been criticized on the ground that it exaggerates the analogies and tends to ignore those features of normative concepts which distinguish them from other modalities.

Wittgenstein did not write very much on the topic of probability. The little we have comes from a few short pages of the Tractatus, some 'remarks' from the 1930s, and the informal conversations which went on during that decade with the Vienna Circle. Nevertheless, Wittgenstein's views were highly influential in the later development of the logical theory of probability. This paper will attempt to clarify and defend Wittgenstein's conception of probability against some oft-cited criticisms that stem from a misunderstanding of (...) his views. Max Black, for instance, criticises Wittgenstein for formulating a theory of probability that is capable of being used only against the backdrop of the ideal language of the Tractatus. I argue that on the contrary, by appealing to the 'hypothetical laws of nature', Wittgenstein is able to make sense of probability statements involving propositions that have not been completely analysed. G.H. von Wright criticises Wittgenstein's characterisation of these very hypothetical laws. He argues that by introducing them Wittgenstein makes what is distinctive about his theory superfluous, for the hypothetical laws are directly inspired by statistical observations and hence these observations indirectly determine the mechanism by which the logical theory of probability operates. I argue that this is not the case at all, and that while statistical observations play a part in the formation of the hypothetical laws, these observations are only necessary, but not sufficient conditions for the introduction of these hypotheses.

● Sergio Cremaschi, The non-existing Island. I discuss the way in which the cleavage between the Continental and the Anglo-American philosophies originated, the (self-)images of both philosophical worlds, the converging rediscoveries from the Seventies, as well as recent ecumenic or anti-ecumenic strategies. I argue that pragmatism provides an important counter-instance to both the familiar self-images and to the fashionable ecumenic or anti-ecumenic strategies. My conclusions are: (i) the only place where Continental philosophy exists (as Euro-Communism one decade ago) is America; (...) (ii) less obviously, also analytic philosophy does not exist, or does no more exist as a current or a paradigm; what does exist is, on the one hand, philosophy of language and, on the other, philosophy of mind, that is, two disciplines; (iii) the dissolution of analytic philosophy as a school has been extremely fruitful, precisely in so far as it has left room for disciplines and research programmes; (iv) what is left, of the Anglo-American/Continental cleavage is primarily differences in styles, depending partly on intellectual traditions, partly owing to sociology, history, institutional frameworks; these differences should not be blurred by rash ecumenism; besides, theoretical differences are alive as ever, but within both camps; finally, there is indeed a lag (not a difference) in the appropriation of intellectual techniques by most schools of 'Continental' philosophy, and this should be overcome through appropriation of what the best 'analytic' philosophers have produced. ● Michael Strauss, Language and sense-perception: an aspect of analytic philosophy. To test an assertion about one fact by comparing it with perceived reality seems quite unproblematic. But the very possibility of such a procedure is incompatible with the intellectualistic basis of logical positivism and atomism (as it is for example to be found in Russell's Analysis of Mind). According to the intellectualistic approach pure sensation is meaningless. Sensation receives its meaning and order from the intellect through interpretation, which is performed with the help of linguistic tools, i.e. words and sentences. Before being interpreted, sensation is not a picture or a representation, it is neither true nor false, neither an illusion nor knowledge; it does not tell us anything; it is a lifeless and order-less matter. But how can a thought (or a proposition) be compared with such a lifeless matter? This difficulty confronts the intellectualist, if on the one hand he admits the necessity of comparing thought with sense-perception, and on the other hand presupposes that we possess only intellectual and no immediate perceptual understanding of what we see and hear. In this paper I give a critical exposition of three attempts, made by Russell, Neurath and Wittgenstein, to solve this problem. The first attempt adheres to strict conventionalism, the second tends to naturalism and the third leads to an amended, very moderate version of conventionalism. This amended conventionalism looks at sense impressions as being a peculiar language, which includes primary symbols, i.e. symbols not founded on convention and not being in need of interpretation. ● Ernst Tugendhat, Phenomenology and language analysis. The paper, first published in German in 1970, by which Tugendhat gave a start to the German rediscovery of analytic philosophy. The author stages a confrontation between phenomenology and language analysis. He argues that language analysis does not differ from phenomenology as far as the topics dealt with are concerned; instead, both currents are quite different in method. The author argues that language-analytic philosophy does not simply lay out of the mainstream of transcendental philosophy, but that instead it challenges this tradition on the very level of foundations. The author criticizes the linguistic-analytic approach centred on the subject as well as any object-centred approach, while proposing inter-subjective understanding through language as the new universal framework. This is, when construed in so general terms, the same program of hermeneutics, though in a more basic version. ● Jürgen Habermas, Language game, intention and meaning. On a few suggestions by Sellars and Wittgenstein. The paper, first published in German in 1975, in which Habermas announces his own linguistic turn through a discovery of speech acts. In this essay the author wants to work out a categorical framework for a communicative theory of society; he takes Wittgenstein's concept of language game as a Leitfade and, besides, he takes advantage also of Wilfried Sellars's quasi-transcendental account of the genesis of intentionality. His goal is to single out the problems connected with a theory of consciousness oriented in a logical-linguistic sense. ● Zvie Bar-On, Isomorphism of speech acts and intentional states. This essay presents the problem of the formal relationship between speech acts and intentional states as an essential part of the perennial philosophical question of the relation between language and thought. I attempt to show how this problem had been dealt with by two prominent philosophers of different camps in our century, Edmund Husserl and John Searle. Both of them wrote extensively about the theory of intentionality. I point out an interesting, as it were unintended, continuity of their work on that theory. Searle started where Husserl left off 80 years earlier. Their meeting point could be used as the first clue in our search. They both adopted in effect the same distinction between two basic aspects of the intentional experience: its content or matter, and its quality or mode. Husserl did not yet have the concept of a speech act as contradistinguished from an intentional state. The working hypothesis, however, which he suggested, could be used as a second clue for the further elaboration of the theory. The relationship of the two levels, the mental and the linguistic, which remained for Husserl in the background only, became the cornerstone of Searle' s inquiry. He employed the speech act as the model and analysed the intentional experience by means of the conceptual apparatus of his own theory of speech acts. This procedure enabled him to mark out a number of parallelisms and correlations between the two levels. This procedure explains the phenomenon of the partial isomorphism of speech acts and intentional states. ● Roberta de Monticelli, Ontology. A dialogue among the linguistic philosopher, the naturalist, and the phenomenological philosopher. This paper proposes a comparison between two main ways of conceiving the role and scope of that fundamental part of philosophy (or of "first" philosophy) which is traditionally called "ontology". One way, originated within the analytic tradition, consists of two main streams, namely philosophy of language and (contemporary) philosophy of mind, the former yielding "reduced ontology" and the latter "neo-Aristotelian ontology". The other way of conceiving ontology is exemplified by "phenomenological ontology" (more precisely, the Husserlian, not the Heideggerian version). Ontology as a theory of reference ("reduced" ontology, or ontology as depending on semantics) is presented and justified on the basis of some classical thesis of traditional philosophy of language (from Frege to Quine). "Reduced ontology" is shown to be identifiable with one level of a traditional, Aristotelian ontology, namely the one which corresponds to one of the four "senses of being" listed in Aristotle's Metaphysics: "being" as "being true". This identification is justified on the basis of Franz Brentano's "rules for translation" of the Aristotelian table of judgements in terms of (positive and negative) existential judgments such as are easily translatable into sentences of first order predicate logic. The second part of the paper is concerned with "neo-Aristotelian ontology", i.e. with naturalism and physicalism as the main ontological options underlying most of contemporary discussion in the philosophy of mind. The qualification of such options as "neo-Aristotelian" is justified; the relationships between "neo-Aristotelian ontology" and "reduced ontology" are discussed. In the third part the fundamental tenet of "phenomenological ontology" is identified by the thesis that a logical theory of existence and being does capture a sense of "existing" and "being" which, even though not the basic one, is grounded in the basic one. An attempt is done of further clarifying this "more basic" sense of "being". An argument making use of this supposedly "more basic" sense is advanced in favour of a "phenomenological ontology". ● Kuno Lorenz, Analytic Roots in Dialogic Constructivism. Both in the Vienna Circle ad in Russell's early philosophy the division of knowledge into two kinds (or two levels), perceptual and conceptual, plays a vital role. Constructivism in philosophy, in trying to provide a pragmatic foundation - a knowing-how - to perceptual as well as conceptual competences, discovered that this is dependent on semiotic tools. Therefore, the "principle of method" had to be amended by the "principle of dialogue". Analytic philosophy being an heir of classical empiricism, conceptually grasping the "given", and constructive philosophy being an heir of classical rationalism, perceptually providing the "constructed", merge into dialogical constructivism, a contemporary development of ideas derived especially from the works of Charles S. Peirce (his pragmatic maxim as a means of giving meaning to signs) and of Ludwig Wittgenstein (his language games as tools of comparison for understanding ways of life). 7. Albrecht Wellmer, "Autonomy of meaning" and "principle of charity" from the viewpoint of the pragmatics of language. In this essay I present an interpretation of the principle of the autonomy of meaning and of the principle of charity, the two main principles of Davidson's semantic view of truth, showing how both principles may fit in a perspective dictated by the pragmatics of language. I argue that (I) the principle of the autonomy of meaning may be thoroughly reformulated in terms of the pragmatics of language, (ii) the principle of charity needs a supplement in terms of pragmatics of language in order to become really enlightening as a principle of interpretation. Besides, I argue that: (i) on the one hand, the fundamental thesis of Habermas on the pragmatic theory of meaning ("we understand a speech act when we know what makes it admissible") is correlated with the seemingly intentionalist thesis according to which we understand a speech act when we know what a speaker means; (ii) on the other hand, to say that the meaning competence of a competent speaker is basically a competence about a potential of reasons (or also of possible justifications) which is inherently connected with the meaning of statements, or with their use in utterances. ● Rüdiger Bubner, The convergence of analytic and hermeneutic philosophy This paper argues that the analytic philosophy does not exist, at least as understood by its original programs. Differences in the analytic camp have always been bigger than they were believed to be. Now these differences are coming to the fore thanks to a process of dissolution of dogmatism. Philosophical analysis is led by its own inner logic towards questions that may be fairly qualified as hermeneutic. Recent developments in analytic philosophy, e.g. Davidson, seem to indicate a growing convergence of themes between philosophical analysis and hermeneutics; thus, the familiar opposition of Anglo-Saxon and Continental philosophy might soon belong to history. The fact of an ongoing appropriation of analytical techniques by present-day German philosophers may provide a basis for a powerful argument for the unity of philosophizing, beyond its strained images privileging one technique of thinking and rejecting the remainder. Actual philosophical practice should take the dialogue between the two camps more seriously; in fact, the processes described so far are no danger to philosophical work. They may be a danger for parochial approaches to philosophizing; indeed, contrary to what happens in the natural sciences, Thomas Kuhn's "normal science" developing within the framework of one fixed paradigm is not typical for philosophical thinking. And in philosophy innovating revolutions are symptoms more of vitality than of crisis. ● Karl-Otto Apel, The impact of analytic philosophy on my intellectual biography. In my paper I try to reconstruct the history of my Auseinandersetzung mit - as I called it - "language-analytical" philosophy (including even Peircean semiotics) since the late Fifties. The heuristics of my study was predetermined by two main motives of my beginnings: the hermeneutic turn of phenomenology and the transformation of "transcendental philosophy" in the light of the "language a priori". Thus, I took issue with the early and the later Wittgenstein, logical positivism, and post-Wittgensteinian and post-empiricist philosophy of science (i.e. G.H. von Wright and the renewal of the "explanation vs understanding controversy" as well as the debate between Th. Kuhn and Popper/Lakatos); besides, with speech act theory and the debate about "transcendental arguments" since Strawson. The "pragmatic turn", started already by C.L. Morris and the later Carnap, led me to study also the relationship between Wittgensteinian "use" theory of meaning and of truth. This resulted on my side in something like a program of "transcendental semiotics", i.e. "transcendental pragmatics" and "transcendental hermeneutics". ● Ben-Ami Scharfstein, A doubt on both their houses: the blindness to non-western philosophies. The burden of my criticism is that contemporary European philosophers of all kinds have continued to think as if there were no true philosophy but that of the West. For the most part, the existentialists have been oblivious of their Eastern congeners; the hermeneuticians have yet to stretch their horizons beyond the most familiar ones; and the analysts remain unaware of the analyses and linguistic sensitivities of the ancient non-European philosophers. Briefly, ignorance still blinds almost all contemporary Western philosophers to the rich, variegated philosophical traditions outside of their familiar orbit. Both Continental and Anglo-Americans have lost the breadth of view that once characterized such thinkers as Herder and the Humboldts. The blindness that has resulted is not simply that of individual Western philosophers but of our whole, still parochial philosophical culture. (shrink)

Deontic logic is standardly conceived as the logic of true statements about the existence of obligations and permissions. In his last writings on the subject, G. H. von Wright criticized this view of deontic logic, stressing the rationality of norm imposition as the proper foundation of deontic logic. The present paper is an attempt to advance such an account of deontic logic using the formal apparatus of update semantics and dynamic logic. That is, we first define norm systems and (...) a semantics of norm performatives as transformations of the norm system. Then a static modal logic for norm propositions is defined on that basis. In the course of this exposition we stress the performative nature of (i) free choice permission, (ii) the sealing legal principle and (iii) the social nature of permission. That is, (i) granting a disjunctive permission means granting permission for both disjuncts; (ii) non-prohibition does not entail permission, but the authority can declare that whatever he does not forbid is thereby permitted; and (iii) granting permission to one person means that all others are committed to not prevent the invocation of that permission.

An increasing number of technology firms are implementing processes to identify and evaluate the ethical risks of their systems and products. A key part of these review processes is to foresee potential impacts of these technologies on different groups of users. In this article, we use the expression Ethical Foresight Analysis to refer to a variety of analytical strategies for anticipating or predicting the ethical issues that new technological artefacts, services, and applications may raise. This article examines several existing EFA (...) methodologies currently in use. It identifies the purposes of ethical foresight, the kinds of methods that current methodologies employ, and the strengths and weaknesses of each of these current approaches. The conclusion is that a new kind of foresight analysis on the ethics of emerging technologies is both feasible and urgently needed. (shrink)

For Kant, the human cognitive faculty has two sub-faculties: sensibility and the understanding. Each has pure forms which are necessary to us as humans: space and time for sensibility; the categories for the understanding. But Kant is careful to leave open the possibility of there being creatures like us, with both sensibility and understanding, who nevertheless have different pure forms of sensibility. They would be finite rational beings and discursive cognizers. But they would not be human. And this raises a (...) question about the pure forms of the understanding. Does Kant leave open the possibility of discursive cognizers who have different categories? Even if other discursive cognizers might not sense like us, must they at least think like us? We argue that textual and systematic considerations do not determine the answers to these questions and examine whether Kant thinks that the issue cannot be decided. Consideration of his wider views on the nature and limits of our knowledge of mind shows that Kant could indeed remain neutral on the issue but that the exact form his neutrality can take is subject to unexpected constraints. The result would be an important difference between what Kant says about discursive cognizers with other forms of sensibility and what he is in a position to say about discursive cognizers with other forms of understanding. Kantian humility here takes on a distinctive character. (shrink)

Future-biased individuals systematically prefer pleasures to be in the future and pains to be in the past. Empirical research shows that negative future-bias is robust: people prefer more past pain to less future pain. Is positive future-bias robust or fragile? Do people only prefer pleasures to be located in the future, compared to the past, when those pleasures are of equal value, or do they continue to prefer that pleasures be located in the future even when past pleasures outweigh future (...) ones? Some arguments against the rationality of future-bias require positive future-bias to be robust, while others require it to be fragile. We empirically investigate and show that positive future-bias is robust. (shrink)

Empirical evidence suggests that people naïvely represent time as dynamical (i.e. as containing robust temporal passage). Yet many contemporary B-theorists deny that it seems to us, in perceptual experience, as though time robustly passes. The question then arises as to why we represent time as dynamical if we do not have perceptual experiences which represent time as dynamical. We consider two hypotheses about why this might be: the temporally aperspectival replacement hypothesis and the moving open future hypothesis. We then empirically (...) test the moving open future hypothesis. According to that hypothesis, we represent the past as objectively fixed and the future open. And we represent that this objective openness moves as events that were open become fixed, such that in doing so, we represent a privileged moving present. We found no evidence for the moving open future hypothesis, which suggests that further investigation of the temporally aperspectival replacement hypothesis is called for. Our results also shed further light on our understanding of the respects in which we represent the future to be open, which, in turn, has implications for our theorising about the open future.

Scientists have the ability to influence policy in important ways through how they present their results. Surprisingly, existing codes of scientific ethics have little to say about such choices. I propose that we can arrive at a set of ethical guidelines to govern scientists’ presentation of information to policymakers by looking to bioethics: roughly, just as a clinician should aim to promote informed decision-making by patients, a scientist should aim to promote informed decision-making by policymakers. Though this may sound like (...) a natural proposal, I show it offers guidance that conflicts with standard scientific practices. I conclude by considering one cost of the proposal: that it would prevent scientists from acting as advocates in a way that is currently common in certain fields. I accept that the proposal would restrict scientists’ political advocacy rights, but argue that the benefits of adopting it — promoting democratic governance — justify the restriction. (shrink)

This is an anthology of ?fteen papers concerning various philosophical problems related to the topic of self-knowledge. All but one of the papers were previously unpublished, and all but two are descendants of presentations at a conference on self-knowledge held at the University of St Andrews in 1995.

Several scholars, including Martin Hengel, R. Alan Culpepper, and Richard Bauckham, have argued that Papias had knowledge of the Gospel of John on the grounds that Papias’s prologue lists six of Jesus’s disciples in the same order that they are named in the Gospel of John: Andrew, Peter, Philip, Thomas, James, and John. In “A Note on Papias’s Knowledge of the Fourth Gospel” (JBL 129 [2010]: 793–794), Jake H. O’Connell presents a statistical analysis of this argument, according to which (...) the probability of this correspondence occurring by chance is lower than 1%. O’Connell concludes that it is more than 99% probable that this correspondence is the result of Papias copying John, rather than chance. I show that O’Connell’s analysis contains multiple mistakes, both substantive and mathematical: it ignores relevant evidence, overstates the correspondence between John and Papias, wrongly assumes that if Papias did not know John he ordered the disciples randomly, and conflates the probability of A given B with the probability of B given A. In discussing these errors, I aim to inform both Johannine scholarship and the use of probabilistic methods in historical reasoning. (shrink)

According to the orthodox treatment of risk preferences in decision theory, they are to be explained in terms of the agent's desires about concrete outcomes. The orthodoxy has been criticised both for conflating two types of attitudes and for committing agents to attitudes that do not seem rationally required. To avoid these problems, it has been suggested that an agent's attitudes to risk should be captured by a risk function that is independent of her utility and probability functions. The main (...) problem with that approach is that it suggests that attitudes to risk are wholly distinct from people's (non-instrumental) desires. To overcome this problem, we develop a framework where an agent's utility function is defined over chance propositions (i.e., propositions describing objective probability distributions) as well as ordinary (non-chance) ones, and argue that one should explain different risk attitudes in terms of different forms of the utility function over such propositions.

Philosophical accounts denying that temporal passage is an objective feature of reality face an explanatory challenge with respect to why it appears to us as though time passes. Recently, two solutions have surfaced. Cognitive illusionism claims that people experience the passage of time due to their belief that time passes. Cognitive error theory claims that we do not experience the passage of time, but hold the belief that we do, which we have acquired through making an inference from the prior (...) belief that time passes. These approaches suppose that belief and passage experience are explanatorily connected, and they depend on the claims that people who experience the passage of time or at least believe that they do also believe that time passes. To test these claims, we probed the beliefs of populations of individuals with depression and schizotypy, thus conditions that are strongly associated with alterations in temporal phenomenology. Depression was assessed with the Beck Depression Inventory (BDI) and schizotypy with the short Oxford-Liverpool Inventory of Feelings and Experiences (O-LIFE). While cognitive illusionism and inferentialist cognitive error theory would predict a strong association between BDI and O-LIFE scores and beliefs about time passage, our study found no such association. The experience of passage does not seem to be explanatorily connected to beliefs about the passage of time. (shrink)

This paper examines the metaphysically modest view that attributionsof normative reasons can be made true in the absence of a responseindependent normative reality. The paper despairs in finding asatisfactory account of normative reasons in metaphysically modestterms.

Laws can be evaluated as better or worse relative to different normative standards. But the standard set by the Rule of Law defines a kind-relative standard of evaluation: features like generality, publicity, and non-retroactivity make the law better as law. This fact about legal evaluation invites a comparison between law and other “goodness-fixing kinds,” where a kind is goodness-fixing if what it is to be a member of the kind fixes a standard for evaluating instances as better or worse. Indeed, (...) for any goodness-fixing kind, K, that sets a standard, S, for evaluating Ks as Ks, we can ask: (1) How does the nature of Ks explain S? (2) Does being a K depend on meeting a minimum threshold of S-relative goodness? In the case of law and its kind-relative standard defined by the Rule-of-Law virtues, these questions lack settled answers. Although Raz (1979, 2019) offers some discussion, I argue that his answers have the surprising upshot of rendering law sui generis relative to other goodness-fixing kinds, and that preserving continuity with other such kinds involves revising the general picture. On the revised picture, law construed as a system of rules is subject to kind-relative evaluation because it is (a) a functional artifact, (b) with an essential function of realizing a limited normative ideal, and (c) its being minimally good at that function—that is, its realization of the relevant normative ideal to some degree—is a condition and ground of law’s existence, since all functional artifacts appear to be subject to such threshold conditions.

This paper explores relationships between environment and education after the Covid-19 pandemic through the lens of philosophy of education in a new key developed by Michael Peters and the Philosophy of Education Society of Australasia. The paper is collectively written by 15 authors who responded to the question: Who remembers Greta Thunberg? Their answers are classified into four main themes and corresponding sections. The first section, ‘As we bake the earth, let's try and bake it from scratch’, gathers wider philosophical (...) considerations about the intersection between environment, education, and the pandemic. The second section, ‘Bump in the road or a catalyst for structural change?’, looks more closely into issues pertaining to education. The third section, ‘If you choose to fail us, we will never forgive you’, focuses to Greta Thunberg’s messages and their responses. The last section, ‘Towards a new normal’, explores future scenarios and develops recommendations for critical emancipatory action. The concluding part brings these insights together, showing that resulting synergy between the answers offers much more then the sum of articles’ parts. With its ethos of collectivity, interconnectedness, and solidarity, philosophy of education in a new key is a crucial tool for development of post-pandemic education. (shrink)

The Bayesian maxim for rational learning could be described as conservative change from one probabilistic belief or credence function to another in response to newinformation. Roughly: ‘Hold fixed any credences that are not directly affected by the learning experience.’ This is precisely articulated for the case when we learn that some proposition that we had previously entertained is indeed true (the rule of conditionalisation). But can this conservative-change maxim be extended to revising one’s credences in response to entertaining propositions or (...) concepts of which one was previously unaware? The economists Karni and Vierø (2013, 2015) make a proposal in this spirit. Philosophers have adopted effectively the same rule: revision in response to growing awareness should not affect the relative probabilities of propositions in one’s ‘old’ epistemic state. The rule is compelling, but only under the assumptions that its advocates introduce. It is not a general requirement of rationality, or so we argue. We provide informal counterexamples. And we show that, when awareness grows, the boundary between one’s ‘old’ and ‘new’ epistemic commitments is blurred. Accordingly, there is no general notion of conservative change in this setting.

Denying the conclusion of a valid argument is not generally permissible if one suspends on one premise of the argument and believes the other premise. This can happen when one’s only critique of an argument is to undermine one premise. There is incoherence there. Here I examine how this is relevant to the debate on evolutionary debunking of our moral knowledge. I argue that one significant line of response to the debunker is unsuccessful: merely undermining the debunker’s empirical claim. It (...) is not rational to respond this way and believe one has moral knowledge. First I present evidence that prominent critics of the debunking argument merely undermine the debunker’s empirical claim. Then I argue for two premises: merely undermining a premise can only justify a middling amount of doubt towards the premise and we should have no more doubt about the conclusion of a valid argument than we do about the premises. Implications of the argument are explored. (shrink)

The main aim of this book is to introduce the topic of limited awareness, and changes in awareness, to those interested in the philosophy of decision-making and uncertain reasoning.

Traditional inflationary approaches that specify the nature of truth are attractive in certain ways; yet, while many of these theories successfully explain why propositions in certain domains of discourse are true, they fail to adequately specify the nature of truth because they run up against counterexamples when attempting to generalize across all domains. One popular consequence is skepticism about the efficaciousness of inflationary approaches altogether. Yet, by recognizing that the failure to explain the truth of disparate propositions often stems from (...) inflationary approaches' allegiance to alethic monism, pluralist approaches are able to avoid this explanatory inadequacy and the resulting skepticism, though at the cost of inviting other conceptual difficulties. A novel approach, alethic functionalism, attempts to circumvent the problems faced by pluralist approaches while preserving their main insights. Unfortunately, it too generates additional problems---namely, with its suspect appropriation of the multiple realizability paradigm and its platitude-based strategy---that need to be dissolved before it can constitute an adequate inflationary approach to the nature of truth.

What features will something have if it counts as an explanation? And will something count as an explanation if it has those features? In the second half of the 20th century, philosophers of science set for themselves the task of answering such questions, just as a priori conceptual analysis was generally falling out of favor. And as it did, most philosophers of science just moved on to more manageable questions about the varieties of explanation and discipline-specific scientific explanation. Often, such (...) shifts are sound strategies for problem-solving. But leaving fallow certain basic conceptual issues can also result in foundational debates. (shrink)

According to Aristotle, the medical art aims at health, which is a virtue of the body, and does so in an unlimited way. Consequently, medicine does not determine the extent to which health should be pursued, and “mental health” falls under medicine only via pros hen predication. Because medicine is inherently oriented to its end, it produces health in accordance with its nature and disease contrary to its nature—even when disease is good for the patient. Aristotle’s politician understands that this (...) inherent orientation can be systematically distorted, and so would see the need for something like the Hippocratic Oath. (shrink)

There are numerous theoretical reasons which are usually said to undermine the case for mental causation. But in recent years, Libet‘s experiment on readiness potentials (Libet, Wright, and Gleason 1982; Libet, Gleason, Wright, and Pearl 1983), and a more recent replication by a research team led by John Dylan Haynes (Soon, C.S., Brass, M., Heinze, H.J., and Haynes, J.-D. [2008]) are often singled out because they appear to demonstrate empirically that consciousness is not causally involved in our choices (...) and actions. In this paper, an alternative interpretation of these studies is offered; one which is in accordance both with the empirical evidence and also with the phenomenology of the will, demonstrating that the two opposing views of agency – both the ones that deny the reality of free will and the ones that affirm it – are equally compatible with the outcomes of these two experiments. On this basis, it is shown that the claim that the results on the timing of readiness potential tip the scales in favour of one or the other view cannot be justified - neither from a neurological, nor from a philosophical perspective.
